    Description

      I have large project with the mix of Qt and boost. I keep upgrading both Qt and boost to the latest available production releases. Currently I am on Qt 4.7.3 and boost 1.47. Recently a new boost build, 1.48 was released. When I compiled my project with this new boost release I started to get multiple errors "Parse error at "BOOST_JOIN", pointing to boost/type_traits/detail/has_binary_operator.hp(50)

      Naturally I thought that this is the boost problem, switched back to 1.47 and problem dissappeared. I posted the report on boost. I also found out that that this issue was already discussed in another boost thread and the conclusion was that it is MOCC bug. I received responses to my boost report where it was stated that the maintainer of the boost library definitely points out to a bug in Qt MOC compiler.

      Following are the links to the discussion:

      Last link suggests workaround for Qt, but it looks to be specific to the software they discuss.

      I believe that it might affect quite a large number of people/projects. I will appreciate if you can suggest a generic workaround to fix this issue.

      Please let me know if I can be of any assistance.
